` `To' all whom t may concern:

Be it vknown that I,JoirN zen of the United States, residing `at Tonopah, in the county of Nye and* State of Neva d'a, have invented certain usefull Improvements in :Universal Jigs, of which the following isv a specification, referencebeing i had therein to the accompanyingjdrawing.

This invention relates to improvements in universal Jigs, one object ofthe-invention being the'provision'of a jig which employs f` hydraulic and hydrostatic principles inxconcentrating ore and ore value movalof the lighter particles;

A further object ofjthisfinvention' is the yand the reprovision of" an apparatus in' which hydraulic pressure in v.a confined; receptacle ljis arranged Aso as t0 operate uponnamoyable: body of ore to remove therefrom the lighter particles which are floated iand 'the smaller heavier.

gf 1vto and embodying the Figs. .5 and c are aan'yawsrjvarius pa`rtments, are the fgagecoclrs 23 which also limit the Water-level above the partition v17 finally to theWater level in the upper compartment 16,l the passage of the Water into the said upper compartment being permitted'by the' provision ofthe gage cocks23 mountedin ythe partition 17.1- These gage cocks yserve to maintain' theproperfvvater llevel at all times since it is to be appreciated ffthat lwhenl orelis deposited'in'v-the jig-boxes it vvill to a certain extent form a substantial closurethat Would'have a tendency to prevent an effective circulation of the Wateru therein be retained -or released, asidevAt the opposite end of 'thetank belovv the l 'partitionf17is an opening 26, in which is mounted the openended 'cylinder 27 which Will'jbe acted upon thereby,4 .f

"pumpglt-he; cylinder 27 being in communica# I `29 carrying the frame'or' -tappet 30 disposed 'inthepathof,l to be engagedby, the cams upon thedr'iven shaft 32.'

The pistonrod-29 is mounted slidablyin aboXing E53- and hasfmountedfuponits ex- 4vten'dedend'ra. coil nspring 34 controlled by` lthe adjustingv 4 member {O15-Which regulates the return VStroke of the' piston' 28..' v

inwardly, While spring y moves the vsame outwardly.'

y"and lit isv desired to use they presentl appara-` tus, the outlet or' discharge pipes l'25` lkare closed, and the'fvalv'e in the feed pipe 24 is When the .Water "has" 'iill'ed Ythe compartment 16 and ,assumes the Water level l indi- `and above the 'partition 17, all Water ybeing @hasta fram- 19am thefpaaaioaae aai 95 jy Thusilby rotatingvthe shaft 82, 'thevv cams engage the tappet'30*andrnoveV the piston 28 iio . through the doors 11, andalso through the' pipe is closed, and then the gage cocks are closed.

The shaft 32 is now operated to impart reciprocatory movement to the piston 28 so as to cause an agitation of the water within` the ycompartment 18 so that an up and down new thereof is caused within the jig boxes.

rlhe jig boxes are now filled with the ore to a point slightly below the water line.

"Every inward thrust of the piston 28 will ment, the return stroke of the piston assistin -g in directing the finer particles through the screen and intoV the compartment, as

aforesaid.

The lighterV particles or gangue inthe jig boxes are now removed with a squaremouth shovel as waste, the heavier concentrates remaining upon the screen.

The jig boxes are again filled with theV orda-nd this operation vis continued `until all or saidboxes are approximately one half full of the concentrates.

At this point, all concentrates are removedl from yall of thejig boxes and placed in'bins by themselves, ythe boxes being again Yfilled with the ore, and this operation continiied'repeatedly. y l Y The compartment 15 does not have to be cleaned' until the accumulation equals a predetermined amount, the Vfiner and heavier particles being held in a static conditionby means of the boardslt and the. action of the agitated water thereabove.

mulated and it is desired to empty the compartment 15, fthe discharge pipes A25 are opened and the water drained. Y v

Access to thebottom is then to be had man holes 12,when'desired.- n

ByA means of the adfustable tappet 30 and the spring 34, varying lengths of stroke may. bel imparted to the piston 28,l according to,`

the weight of the ore treated.

approximately from sixty to one hundred strokes per/minute, and as shown, the shaft,A

32 may be provided with loose and fast pulleys for belt driven, or lin fact, with any,V other mechanism `by means of which the..

same may be rotated and controlled.

In localities where waterrisga prbblem, that drained from the compartment 15 by the 4valves 25 may be saved and used again, the uppermost valves 25 being vopened first, and so on, until all or the saine are opened and the full amount of water discharged.,

the gage cocks 23 having been previously opened to permit of the easy flow or the water.

It will be pointed out that the spring Btis adapted for storing energy from the motive power so as to operate upon the pistonfrod 23 and its piston 28.` v

lVhen the camsl act upon the tappet 30 the said spring '34 is tensioned, when the cams 31 ride off the tappet 30, and the said cams release the tappet, the spring becomes l active to move the piston 28 outwardly from the cylinder 27, thereby giving a rapid action to the piston for creating sudden suction within the jig box,.which serves to pre.-

cipitatethe heavier particles of mineral through lthe soreensinto :the tank bottom, so that in this manner the heavy'v sliines and heavier particles willbe drawn through they screens toy be delivered in the tank bottom, aswill be clearlyapparent What lI, claim as new is 1. ln a universal jig, thecombina-tion of a tank, a horizontal partition extending, throughout the. lengthy of the .tank adjacent the upper` edge and dividing the'tank into lupper and lower Vcompartments. and having a Yplurality of openings therein, jig boxes supported in the openings having perforated bottoms,l a plurality of static -boards hinged at one of theirfends to one of the sides of the tank in the lower compartment and also arranged in close relation with the biot- .tom, a plurality of gage cocksinounted in, the partition 4establishingV communication between the upper andy lower compartments,
